【Abstract】 The high-chloride chemical wastewater was pretreated using Fenton reagent. The dominant influencing factors were discussed and the optimal technological parameters were determined. The results showed that the COD removal rate was more than 64% and the B / C increased from 0. 016 to 0. 35 under the conditions of pH value of 4. The dosage of H 2 O 2 was 325 mmol. The dosage of FeSO4 was 20. 8 mmol and the reaction time was 90 min for 250 mL wastewater. The quality of the water was improved obviously and favorable to the latter biochemical processing.更多还原
